How are individual trees built in a Random Forest? Group of answer choices Each tree is trained using a bootstrap sample of the dataset, and feature selection is performed randomly at each node split. Each tree is trained using the entire dataset, and feature selection is performed randomly at each node split. Trees are built using a greedy algorithm that maximizes information gain at each node split, considering all features at each split. Trees are built using a pre-pruning strategy to limit tree depth and prevent overfitting.
Using the data in the following tables, let matrix A represent imports (in billions of dollars) to the U.S. from country groupings, and let matrix B represent exports (in billions of dollars) from the U.S. to country groupings. Find the U.S. trade balance with each country grouping in each year by finding matrix B - A. Imports to U.S. from Country Groupings ($billions) 2000 2002 North America 366.8 363.0 Western Europe 260.7 246.0 South/Central America 73.3 89.5 Pacific Rim 418.0 413.5 Exports from U.S. to Country Groupings ($billions) 2000 2002 North America 290.3 278.4 Western Europe 181.5 177.0 South/Central America 59.3 51.6 Pacific Rim 222.6 198.6 B-A North America 132.6 141.1 Western Europe 76.5 84.6 South/Central America 79.2 69.0 Pacific Rim 149.3 214.9
